Definitions

  • the invention relates to a method for controlling nematodes with salts of sulfur-containing compounds.
  • Halogenated hydrocarbons continue to have the aforementioned problems for humans and the environment.
  • parasitic nematodes can be used in lawns and golf courses (Crow, 2009).
  • Methionine salts are commercially available in the form of existing market products such as Liquimet or are technically involved in the production of methionine in the
  • solutions prepared by dissolving methionine in alkali / alkaline earth solutions can also be used.
  • Methionine itself must be used in very dilute form because of its poor solubility, but e.g. 5 to 75% solutions, in particular 10 to 50% solutions find use. If the user works with commercial methionine, in order to avoid high dilutions, he must apply suspension, which has the disadvantage that the solids sediment and thus a uniform application of the substance can be difficult to impossible.
  • alkali metal methioninates or
  • Alkaline earth methioninates more preferably Na-methioninate or K-methioninate or mixtures thereof.
  • the pH of the solutions is generally> 8, preferably 8 to 11.5.
  • Cultures of plants, especially cultures of ornamental plants, are generally treated according to the invention.
  • Methioninattersen containing 5 to 75 wt .-% methioninate, preferably 10 to 50% by weight, particularly preferably 10 to 30 wt .-% directly to the Soil or the plants it is possible to simplify the use of methionine as a nematicide significantly.
  • Methioninate as nematicide in the form of the soluble salts themselves or as mixtures of these with fertilizers and / or other pesticides products such as herbicides, insecticides, fungicides, microbiocides or growth regulators.
  • Fig. 1 shows the solubility of DL-methionine at 25 ° C and different pH values and bases.
  • the measurement was carried out as follows: At 25 ° C., 200 g of DL-methionine were suspended in 200 ml of demineralised (DI) water. After stirring for 30 min, 1 ml of a sample was taken, filtered and diluted with the aid of an Eppendorf pipette by a factor of 1000 with deionised water. This sample was analyzed by HPLC. It was then adjusted to the next pH with the appropriate aqueous base (50%) and stirred for a further 30 minutes before a sample was taken. Optionally, further solid methionine was added to add a supersaturated solution
